The existence, development, and continuing survival of human life is nothing short of incredible. This is especially true when we consider how many different factors had to come together to make life here on earth possible. There is no more obvious example of this ideal melding of variables than in the air around us. We all remember our basic science from school. As far as our human body is concerned, we can take or leave the gas nitrogen.

The importance of the physiology and toxicology of oxygen O 2 breathing have increased in recent years. For example, currently, strategies to protect the lung from mechanical injury during mechanical ventilation emphasize the use of lower tidal volumes. But such strategies may impair gas exchange, resulting in higher requirements for inspired O 2 fraction F I O 2. Gilbert 6 postulated that in this primordial reducing atmosphere, the first living cells used hydrogen, diffusing into the cell from the environment, as an energy source e.

Last column we focused mainly on the mechanisms of oxygen toxicity. This column will continue that discussion with a description of the toxic effects of oxygen on the lungs and the brain. The discussion is fairly technical so it would be advisable to review the last column before continuing with this one. Lorrain Smith first described the toxic effect of oxygen on the lungs in He noted that the severity of the effect increased with increasing pO2 and that the effects where largely reversible.

Overdose on Oxygen?

Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen O 2 at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs , and eyes. Historically, the central nervous system condition was called the Paul Bert effect , and the pulmonary condition the Lorrain Smith effect , after the researchers who pioneered the discoveries and descriptions in the late 19th century.

Remember Me. Sign Out. Her pulmonary examination was unremarkable. The chest radiograph revealed bilateral lower lobe infiltrates. The patient was admitted with a diagnosis of community-acquired pneumonia and a COPD exacerbation. She was given appropriate therapies and, with her mild illness, was expected to be discharged the following day. On the morning following admission, she was found to be somnolent and minimally arousable.

The clinical settings in which oxygen toxicity occurs is predominantly divided into two groups; one in which the patient is exposed to very high concentrations of oxygen for a short duration, and the second where the patient is exposed to lower concentrations of oxygen but for a longer duration.
